The alfalfa leafcutting bee, Megachile rotundata: the world's most intensively managed solitary bee.
The alfalfa leafcutting bee (ALCB), Megachile rotundata F. (Megachildae), was accidentally introduced into the United States by the 1940s. Nest management of this Eurasian nonsocial pollinator transformed the alfalfa seed industry in North America, tripling seed production. The most common ALCB management practice is the loose cell system, in which cocooned bees are removed from nesting cavitie...
متن کاملTranscriptional responses to fluctuating thermal regimes underpinning differences in survival in the solitary bee Megachile rotundata.
The transcriptional responses of insects to long-term, ecologically relevant temperature stress are poorly understood. Long-term exposure to low temperatures, commonly referred to as chilling, can lead to physiological effects collectively known as chill injury. Periodically increasing temperatures during long-term chilling has been shown to increase survival in many insects. However, the trans...
متن کاملOocyte size, egg index, and body lipid content in relation to body size in the solitary bee Megachile rotundata
Females of solitary, nest-provisioning bees have relatively low fecundity, but produce large eggs as part of their overall strategy of investing substantially in each offspring. In intraspecific comparisons of several species of solitary, nest-provisioning bees and wasps, the size of the mature eggs produced increases with female body size. We further examined oocyte size-body size correlations...
متن کاملAlternation of Sex Ratio in a Partially Bivoltine Bee., Megachile rotundata (Hymenoptera: Megachilidae)
Data on offspring production by the alfalfa leafcutting bee, Megachile rotundata (F.), from three site-years were used to examine predictions of parental investment and sex ratio theory. In northern Utah, spring-emergent adults produce two types of offspring: those that develop directly to the adult stage and emerge in midsummer, and those that develop to the prepupal stage and enter diapause u...
متن کاملDiscrimination of closed shapes by two species of bee, Apis mellifera and Megachile rotundata.
In the present study, the performance of two bee species, the honeybee Apis mellifera and the leaf-cutter bee Megachile rotundata, in discriminating among various closed (convex) shapes was examined systematically for the first time. Bees were trained to each of five different shapes, a disc, a square, a diamond and two different triangles, all of the same area, using fresh bees in each experim...
